screen brightness

Q:screen brightness

HiI can't adjust my screen brightness. I right-clicked on the desktop and selected Display Settings and the brightness adjustment bar was moveable, but it had no effect. Now, when I right click and select display settings, the brightness adjustment bar is no longer there.Currently the display is too bright and is quite glaring causing eye strain.Any help would be welcome.ThanksDaniel

Hi I have Dell Inspiron13 7000 series laptop.Everything was working fine until 2 weeks back.Suddenly I wasn't able to use F11/F12 keys to controll brightness.Even if I clicked I wasn't getting the actual brightness bar.I checked some blogs and youtube videos, which helped me and it fixed my issue.Suddenly after almost a week or so, I am getting another issue.I can scroll up or down the brightness however it doesn't change any brightness level.Right now it is too bright but I can't change it.Has anyone been facing this issue or resolved this?Laptop was in perfectly operating condition before.I have been getting these issues recently after regular windows update.

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider. It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting, then it goes right to minimum. I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

Does anybody know what drivers/software is responsible for displaying On Screen Volume and Screen Brightness Indicator (while pressing Fn+F2,F3,...) ?

What I've found so far that the Dell QuickSet may does the work (link to this solution: No Level Indicator When Using Keyboard Audio Volume Controls), but I couldn't find a compatible version of this soft with Dell Latitude E5550.

I'm running Windows '98 on a 'Tiny' tower system and monitor.I recently reinstalled Windows on my sysytem following virus problems which have now been solved.

Before reinstalling Windows I was having problems with the brightness of my screen - basically it was very dark - which I was correcting by going to [Settings],[Control panel],[Display], [Setting], [Advanced], [Color] and changing the settings there.

Now I've reinstalled Windows I've lost the [Color] tab on the [Advanced] window and I'm unable to brighten my display.

My display driver is the most up to date available in the windows database - please help me change the brightness of my display.

I've noticed this happen twice. All of a sudden the screen flickered for just a second and the colors on the screen got brighter. By brighter I mean the the actual color changed (ex. my blue taskbar looked grayish). Both times my laptop was plugged in and the second time it happened I simply unplugged the computer and it changed back. After plugging the adapter back in the screen went to plugged in settings, but did not change the colors. The two times were separated by about two weeks.

I'm curious what might be causing this. It's probably just some little bug with a driver but I wanted to know what you guys thought.

A:Screen Brightness

Try uninstalling the monitor driver, re-booting, and letting it re-load the driver when it loads.

I have a very small problem here. I had a recent format to my laptop. Assume now that I am working on the battery. Whenever I plug in the AC, screen brightness increases perfectly. No problem here. Now imagine, I put the laptop to sleep or hibernate and I plug in the AC. Whenever the laptop comes from sleep or hibernate, screen brightness stays dimmed. I need to adjust it manually every time.

Did any of you experienced something similar to this one? I checked other posts but most of them are related with not being able to change the brightness manually. Nothing like my problem.

I appreciate any suggestion

I am seriously thinking of purchasing a P51 and am concerned about some feedback regarding the 4K (3840x2160) screen being dimmer than other 4K screens. ( https://www.laptopmag.com/reviews/laptops/lenovo-thinkpad-p51). My current display on my T530 is set at 80% brightness which is just fine; any higher percentage is too bright for me. The reviews of the P51's 4K screen seem to have a common complaint of not having as good a range of brightness. Any first hand feedback would be much appreciated.Thanks,Altoid666

The P51 screen is brighter and also has almost no grain. That said, I would still like the P51 4K screen to be brighter than it is, but then I am a succer for bright screens also and is used to the XPS15 4K and MacBookPro 15 screens which are both the best in the business (Surface seems to be good to but have never used one). Its not like it is a problem to use the screen even in a quite bright room, but it is a bit "dull" compared to the ones mentioned above.

I am a teacher and we use chrome books daily. However, I have 4 chrome books that have the exact same problem. It looks like a black screen, however the chrome book is turned on and brightness is at 100%. I can barley make out that the computer is working, however if I conect it to the projector I can see the display. Thank you

Hi: Did you install the graphics driver? That would be the only suggestion I can offer. This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp75501-76000/sp75508.exe Check to ensure you see the Intel graphics adapter listed in the device manager under the display adapters device manager category. If you see a Standard VGA Adapter, that means the graphics driver did not install.

I have a Lenovo y560 and the screen brightness juss keeps changing on its own, i try to set it to a brighter settingand it justs lowers itself back down within seconds, the laptop is also running windows 7 64 bit if that could be a cause.

A:Screen brightness changes on its own?

Your computer's got an ambient light sensor to detect and automatically adjust screen brightness based on surrounding lighting. You'll have to disable the setting. Lenovo has their own energy management program that has a setting for it, but I'd imagine there's something in the Control Panel (maybe Power Options?) that allows you to turn the setting off.

I can hardly see the screenIt just goes down on its own.I to have some control oer the brightness, and have got it set NOT to go to sleep on or off the battery.It's a full whack now, and it's still not bright enogh.Its just started doing it since i had to get my system re-set. I used to do it befoer but I managed to get it so that it didnt do it on its own.I checked in power serttings and i defintiely do not have it set to go dim after a while.Would love some help cos its too dark and hurting my eyes at the moment.thanks

Are you using an HP branded power adapter? Cheap generic ones, can cause power fluctuations.

I upgraded to Windows 10 and now the screen is too bright. The buttons when used don't adjust the screen brighness at all. I upgraded the drivers and it still does not work. Any suggestions or has anyone else has this issue?

I have just gone from Win XP SP3 to Windows 7. Two nights ago is when I installed windows 7 everything was fine then after restarting my netbook my screen brightness went down so I went to download the utility tool for my Display Manager. Other hotkeys work perfect just not my brightness.

When my netbook starts up I can change the brightness up from one bar to two bars (20%) but no more. I have even reinstalled the tools again but nothing works for my brightness and there is nothing on the power options for the brightness.

hi, i hope you guys can help me with this.....i upgraded to windows seven and love it. there has only been one big problem....when i unplug my dell inspiron 1720 laptop the screen dims significantly.....and the button on my lap top wont make it brighter. When i click the battery button "adjust plan brightness" is up all the way for running on battery.....any help....i use it alot not plugged in school and its way to dim to use like this...JOHN

A:Screen Brightness

The first step would be to see if there any Win7 drivers for your computer.I did not see any .... Yet...Maybe the vista 32 drivers will work for now.

I've tried a bunch of things, but the maximum brigntnes on the LCD screen of my E1505 is still very dim compared to a regular VGA LCD monitor. I tried changing things in the ATI Catalyst driver (and the UP/DOWN brightness funcion on the keyboard) but it's still very dim. I'm getting frustrated... any ideas guys?

My desktop machine is a Windows 7 32-bit. My problem is that when I read a PDF, the brightness of screen bothers me and I want to reduce it. My monitor is a Samsung LCD and only has a button. When I press it one time it turn the screen on/off and when I press and hold it, it just adjusts the wallpaper.

Is there a way to reduce it?

A:How to reduce my screen brightness

Your going to have to post the exact model of your monitor for us to help you because its going to be the monitor that reduces the brightness.

I'm not sure if this is in the right forum. But in the last couple months, once in a blue moon I couldn't change my screen brightness, and now in the last couple days it's gotten a whole lot worse. Usually, I can't change brightness either via my 'fn -/+' hotkeys or via the actual brightness slider in the power panel. A full reboot or simple hibernation then reboot both let me change brightness again. But the last couple days, restarting the computer just puts the brightness on either fully dimmed or fully bright, and I still can't change it.

This is an HP G60 laptop, and I've had windows seven for a year on it. Like I said above it only started a couple months ago then got worse this week, and what I've found on google so far was all for newly-updated-to-seven issues. My drivers all seem to be up to date according to the windows update driver function... Can anyone help me?

since a reboot fixes it (at least temp.) it is probably not hardware but software. Do you have a backup from before the problem started getting worse?

Hi, i've upgraded to windows 7 recently on my laptop and i think that it's really great compared to vista.

I have no problem with most of the things except for the ability to adjust brightness.I could not change brightness the way i used to by using the FN + left/right key, nor the slider in power options menu.

The screen seems to be at the maximum brightness,which in turn causing my eye to hurt after some time of usage.

Any idea why? I need some help here.Btw i am using Aspire 6935G.

it's likely you will need to install a utility for that control to work

Ok did some searching , goto the acer website\ support and pick > notebook > aspire > 6935G > then pick your Operating System and make sure you have all the drivers and applications they list

I like my Toshiba Portege M300 because of compact size, etc. Recently I needed a new hard disk and my repairer loaded W7. I used XP previously and Toshiba do not recommend W7 for this notebook due to age. However, all is working well apart from the screen brightness adjustment. This was previously done by the Fn+F6/F7 hotkeys and there was a driver for this.

In W7 Screen Resolution there is supposed to be a brightness slider but this is not present on my W7 system (I gather that this not an uncommon feature)

How can I adjust the setting sin my notebook to fix a brightness as I am resigned to the fact that the old brightness adjustment will not apply now that I am using W7? Is there a change in the Bios that might help?

A:Screen Resolution Brightness.

I didn't think that the brightness settings of Fn+F6/F7 were affected by the OS but I've been wrong about stuff like that before

In the BIOS, there should be some kind of power or battery settings section that may have some LCD brightness settings that you can try tweaking.

Dear All! A few weaks ago I bought a new HP ProBook 440 G3 notebook and everything is working perfectly, only the FN keys for screen brightness are not working (the other fn keys for volume etc are OK).

Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.

What do I do?

A:Screen Brightness won't adjust

Contact the shop that did the replacement, and ask them why it doesn't work now.

In the spring of this year, I sent my laptop in to HP for repair as the screen was black on startup. I was specifically told not to send the power cord. I reinstalled all my programs when it returned. The problem persisted and it was recommended to do a system restore. This did not help, so I contacted HP again with the same problem. Only now I know that if you set the screen brightness to minimum on battery, it will remain bright when you plug in the power cord. A tech at HP gave me the solution. Disable and then Enable the Display Adapter. Wonderful. It works. THE ONLY PROBLEM IS I HAVE TO GO THROUGH THIS PROCESS EVERY SINGLE TIME I POWER UP! I have to power up on battery only, Go through the process AND THEN plug in the power cord to keep the screen lit. ANY SUGGESTIONS? Thanks for any help you can give me.

I have gone into the control panel and tried changing the screen brightness but nothing seems to work. I am the system administer so I should be able to set all changes. Hope you can give me some direction.

Hi. I can't figure out how to disable auto brightness feature on my laptop. It's dell xps 15 with 1080p display. It happens on battery only, on every power plan. I don't mean the display dimming after a certain time, but it just goes from bright to dark. The darker the image, the darker the screen dimms and vice versa. I had another problem which was the colors going crazy when the sceen went back on after unplugging charger or waking it on battery (it all went down to what was like 256 color range). This problem was resolved after unchecking "Intel Display Power Saving Technology" in Dell Quick Set. Yet I can't get rid of the auto screen dimming which is extremely annoying. Has the laptop got an ambient light sensor or something? Please advise.
PS. I all seems like there's an ambient light sensor which is trigggered by the brightness of the screen itself and it shouldn't work like that.

First of all, please specify maker and model of your laptop. Some vendors could have their own third party replacements for some functions.

Also, please go to Control Panel - Power Options - on the right side of your current active power plan select "Change plan settings" - in the next window click "Change ADVANCED power settings" - then navigate to - Display - Display brightness and check percentage.

Hi! My Lenovo Yoga 710 14-IKB is now stuck on medium brightness and I canīt change it. I have tried to disable and enable generic PhP drivers and rebooting. Brightness adjusting was working fine 3 hours ago but now when I booted up my laptop, it wasnīt working.

My screen on my workhorse and much loved T500 -- 1680 x 1050 resolution -- is getting dim. Although this model includes the AMD Radeon HD3650, the driver had to be disabled to switch to Windows 10. W10 works great without the AMD adapter. So, I can't use Radeon software to adjust brightness above the default setting. Any other ideas? I guess that a new LCD panel would restore brightness (if I can find the right one at a reasonable price). I'm open to suggestions. No, I don't want to use an external monitor. Thanks for any help that come my way. Nobarking

A:T500 screen brightness

I know this is a couple of years old, but did you ever find a solution?. My T500 (2241-CTO) is getting dim as well, but the screen quality is so much better than any of the more modern Thinkpads I have, so don't really want to replace it. I'm currently thinking of going full techy and replacing the CCFLs, or maybe even attempting a CCFL to LED conversion, if that's possible.

On my monitor it seems like everything is too bright, as in places that should be pitch black are a bit too light. For example: on my iPod, even with full brightness settings everything looks normal, but on my PC's monitor it just doesn't look right.

I calibrated color and setting gamma way low really helped, but my contrast is set to full, and my brightness is 75.

The strange thing: when I ran Crysis 1, it fixed the monitor color! So I know the darn thing is capable, I just don't know how to.

Hi, Here are some common ways to adjust the brightness. Open windows Control Panel, open Windows Mobility Centre and adjust the brightness here. On a lot of notebooks, tapping f3 will often increase the brightness ( with f2 reducing it ).

So I have read a lot of diffrent ways to solve this problem and I have searched for hours looking for a solution, yet nothing i've tried has worked for me. Whenever i press the fn key and try to adjust brightness then it does't, it does pop up the slider at the corner but it only moves upwards and downwards only one level yet the brightness wont change even that much. I only found one other person that had this problem and he got it solved, but he had an Asus laptop and he got it fixed with some Asus drivers but i have a Dell Vostro laptop. One of the biggest suggestions i have found that has worked for people has been to install some older display drivers, but that hasn't worked for me either.

I have a problem wtih the screen brightness on my laptop. The problem is that the screen looses brightness whenever I plug-in or plug out the charger. In the display brihtness menu I have set the maximum brightness for every power plan - just in case and in advanced options I have disabled the dimming option. But the screen still looses brightness every time I plu -in or remove the charger. So I have to change the brightness manualy every time. And when I do so, lower the brightness but the brightness actually increases and I am clueless what to do.
